The Junior is a small portable tube luminometer designed for all common applications using glow-type bioluminescent and chemiluminescent reagents.

Its small size and low weight, paired with battery operation make the Junior a highly versatile instrument which can be used in any location – the laboratory, on site or outdoors. The Junior is used in a number of diverse fields of application including biomedical research, clinical diagnostics, hygiene monitoring, process control in biotech and environmental monitoring of water quality.

• The detection unit is a state-of-the art ultra fast single photon counting photomultiplier with
  low noise.
• Single photon counting electronics and selected photomultiplier tubes with low noise and high saturation level, ensure a wide dynamic range without the need to change any settings.
• A stringent selection of detectors ensures a negligible day-to-day variation of instruments,
  providing high measurement reliability.
• The unique design of the measuring chamber allows the use of a variety of different sample tubes and sizes. Besides the traditional lumi vials, microcentrifuge tubes (Eppendorf cups) and capped
  4 mL vials can be used.
• Equipped with rechargeable batteries so it can operate independently from a main power supply for many hours. Reconnect to a main power supply to automatically recharge the batteries.
• Small in size and lightweight (only 2 kg), the Junior can be taken to the sampling location for measurements on site. A metal transport case is available for the Junior and accessories,
  and is an ideal solution for outdoor use.

Easy-to-use
The lean and dedicated software is operated through a membrane keypad. The well arranged graphical display shows selected protocol, sample location and number, and the RLU value of the measurement. In addition, a red, a yellow and a green LED unmistakably indicates whether a signal a sample is above an upper limit (red), below a lower limit (green) or in between (yellow).

Smart
Up to 2,000 measurement results will be stored in the instrument’s memory. Criteria like time of measurement and the measurement location may be used to search for results in order to review them.
The same criteria may be applied to select results for being downloaded to a computer. The PC software Winterm arranges the data properly and transfers it into an EXCEL spreadsheet.
